Como puedo implementarlo en mi WEB
A ver:
Estas en un server con Soporte PHP?
Si la respuesta es si:
Script Ejemplo:
(getpost.php)
Código PHP:
<?php

Sube este script a tu server y te mostrara los ultimos post de este foro, ademas un limk para ir al hilo de cada uno...
Espero no haberte abrumado con esto, nec. aprender algun lenguaje de secuencia de comando (ASP - PHP) para sacar partido a los RSS...
